  • Patent number: 10706820
    Abstract: A system may produce a multimedia presentation that includes visual stimuli, auditory stimuli, olfactory stimuli, thermal stimuli and air currents that are perceptible to a human user. All or part of the system may be housed in or affixed to a table or desk. Sensors may monitor physiology or activities of the user and provide feedback regarding the user's response to the presentation. A user may input instructions for the system. Based on these instructions, the system may present a multimedia presentation which tends to produce a target physiological state of the user that is specified in the instructions or which tends to maintain a current physiological state of the user. The system may employ a control space to control the presentation. This control space may have axes that correspond to how a user perceives multimedia presentations.

  • Patent number: 10708992
    Abstract: Camera images may be analyzed to identify perceptual control axes for a lighting system. These control axes may correspond to how human users perceive lighting scenes. A camera may capture high-dynamic-range images of a new room under various lighting conditions. Dimensionality-reduction may be applied to the images to create an image-based map. In this map, each datapoint may correspond to one of the images. The map may be transformed to align it with how human users perceive lighting scenes in the new room. The transformed map may be employed as a control space for the lighting system. In some cases, the map is created without gathering user ratings of lighting scenes for the new room. In other cases, creating the map involves gathering user ratings for as few as three lighting scenes for the new room.

  • Patent number: 10705706
    Abstract: Closed loop control of a multimedia system may be achieved with a control space that includes at least two control axes. In each control axis, a coordinate on the axis may indicate a degree to which a multimedia scene facilitates or is perceived to facilitate a user state or a degree to which the user state is achieved. For example, the two control axes may be focus and restoration. A user may provide input that specifies a target state. The target state may be different than, or the same as, the user's current state. The system may select a scene that has coordinates, in the control space, that are closest, by at least a threshold, to the target state, and present the scene to the user. Sensors in the system may measure a user state that results from presenting the scene. The system may revise the scene's coordinates accordingly.

  • Patent number: 10542581
    Abstract: The present invention relates to a technology for managing discontinuous reception (DRX). DRX cycles of different cycle lengths are configured according to service types of UE. If it is identified that the user equipment (UE) initiates a voice service, a relatively short first long DRX cycle is configured for the UE or the UE is instructed to deactivate DRX; and if it is identified that the UE does not perform a voice service, a relatively long second long DRX cycle is configured for the UE. The UE performs corresponding receiver on/off control according to the configured long DRX cycle, so as to receive downlink data or hibernate. According to the solution provided in the present invention, a DRX cycle of UE can be flexibly configured, so that a better balance between power consumption reduction of the UE and user experience improvement can be achieved.
